Title: Video tape recorder
Inventor: TOMITA MASAO
IPC: H04N5/91
Filed: 1982-08-31
Abstract: PURPOSE:To offer a long-play sound recording function having a good quality at a low cost, by having a mode in which recording and reproducing are executed by a rotary head by frequency-modulating a sound signal. CONSTITUTION:In case when a changeover switch 15 and 16 are connected to a VTR side, a titled video tape recorder has all the same constitution as a conventional VTR. In case when the switches 15, 16 are set to an AUDIO side, a sound signal applied to a terminal 19 is subjected to FM by a sound FM processing circuit 17, reaches a sound recording and reproducing switch 10 through the changeover siwtch 15, and in a recording state, its signal is supplied to a rotary head 11 and 12, and sound recording having an excellent S/N ratio is executed on a video track on a magnetic tape 7. When the sound recording and reproducing switch 10 is in a reproducing state, an FM sound signal picked up by the rotary heads 11, 12 is demodulated by a sound FM detecting circuit 18, is reloaded to its original sound signal, and a sound reproducing signal having a good quality is outputted to a terminal 20.

Title: Motor cooling fan
Inventor: WATANABE KUNIO
IPC: H02K9/06
Filed: 1995-05-26
Abstract: PURPOSE: To reduce the noise of a motor cooling fan even when the fan is rotated in the opposite direction by constituting the fan so that its vanes can blow air in such a state that the vanes are inclined backward to the left or right side around a shaft and the vanes are stopped in an inclined state by means of a stopper. CONSTITUTION: While the variable vanes 10 of a fan are fixed to a pipe 15, the main plate and side plate 12 of the fan are not in contact with each other. A shaft 13 is passed through the pipe 15 and fixed to the main and side plates 11 and 12. Although the pipe 15 is brought into contact with the shaft 13, the pipe 15 can rotate around the shaft 13 together with the vanes 10, because a small clearance exists between the pipe 15 and shaft 13. When the fan starts to rotate counterclockwise, the vanes 10 are inclined backward to the right side around the shaft 13 by a wind pressure, but stop when the vanes 10 come into contact with a supporting bar 14b. The fan continuously blows air in the inclined state. When the fan rotates clockwise, the vanes 10 are inclined backward to the left side around the shaft 13 and stop when the vanes 1 comes into contact with another bar 14a.  The fan continuously blows air in the inclined position.

Title: Control device for automatic clutch of vehicle
Inventor: OOKUMO HIROYA
IPC: B60W10/10
Filed: 1986-06-28
Abstract: PURPOSE:To make starting performance satisfactory by detecting a stall condition based on both a clutch engagement rate and engine speed changing rate whereby making a correction in such a way that an actual clutch control value corresponds with a value corresponding to a set stall revolving speed. CONSTITUTION:Engine revolving speeds Ne and Nc at input and output sides are inputted into a clutch engagement rate computing section 44 so as to obtain a clutch engagement rate E whereby said engagement rate E and revolving speed Ne are inputted into a stall condition detecting section 45 so as to judge a stall condition. Then, under the stall condition, an actual control value is compared with a value corresponding to a set stall revolving speed whereby a correction is made based on a deviation between both values so as to set a set stall revolving speed. Accordingly, stall revolving speed at the time of starting becomes the set value, thereby usually obtaining satisfactory starting performance.

A regulating wall 13 is provided protrusively inward a combustion chamber 4 in such a way as to enclose the upper part of the recirculation valve 12. The recirculation valve 12 is opened in the terminal stage of a suction stroke or the initial stage of a compression stroke so as to let a part of exhaust gas flow as recirculation gas R into a cylinder 1 from an exhaust passage 6. At this time, however, the recirculation gas R impeded in its upward inflow by the regulating wall 13 flows downward along the inner face of the cylinder 1 and further along the upper face of a piston 2, and also only fresh air M is converged around a spark plug 9. Desirable ignitability can be thereby obtained, and heat efficiency is enlarged.

Title: Manufacture of stainless steel strip for spring or cold-rolled stainless steel strip for spring
Inventor: ARAIKE HIDEKAZU
IPC: B21D1/05
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To improve a spring limit value under condition that the reduction ratio in finish rolling is taken as >=20% to a stainless steel strip for springs or cold-rolled stainless steel strip for springs. SOLUTION: After executing finish cold rolling at the reduction ratio of >=20% to the base stock of the stainless steel strip, the base stock is passed through a roller leveler. It is desirable to take the number of rolls 6 of the roller leveler 3 as 8-25 and to set tension of the roller leveler in the range of 2-20kg/mm<2> in accordance with the number of the rolls. By passing the base stock through the roller leveler, the skin part of the material is plastically deformed by repeated bending with small diameter rolls, internal stress is reduced, fractionated and made to approach uniformity and residual tensile stress on the surface is lowered, so the spring limit value is raised.

Title: Ammonia combustion engine
Inventor: KOREMATSU KOJI
IPC: F02M25/10
Filed: 1991-06-25
Abstract: PURPOSE:To improve combustibility by providing an ammonia decomposition reacting means which decompose ammonia by the exhaust gas after combustion in an ammonia combustion engine which obtains driving force by combusting ammonia gas. CONSTITUTION:The ammonia gas in an ammonia tank 22 is introduced to a combustion chamber mixed with the air in an intake pipe 14. Since ammonia gas is incombustible in the combustion chamber 24, gas such as hydrogen gas is introduced in a sub-combustion chamber 64 to perform initial combustion. Since in the beginning of combustion in the combustion chamber 24, the temperature of the exhaust gas introduced in an ammonia decomposition reactor 38 is also low, a heat exchanger 42 is heated by an auxiliary heater 52 to decompose the ammonia gas into nitrogen and hydrogen. This hydrogen is sent to the combustion chamber 24 and a hydrogen occluding means 58. In the case of lacking in hydrogen supply amount in starting an ammonia combustion engine 10 and rapid acceleration, the hydrogen reserved by the hydrogen occluding means 58 is supplied to the sub-combustion chamber 64. This improves the combustibility of ammonia.
